The Chicago Tribune reports (non-paywall article on the same news here):

One by one, five police officers took the witness stand at the Skokie courthouse late last month for what would typically be a routine hearing on whether evidence in a drug case was properly obtained.

But in a "Perry Mason" moment rarely seen inside an actual courtroom, the inquiry took a surprising turn when the suspect's lawyer played a police video that contradicted the sworn testimony of the five officers — three from Chicago and two from Glenview, a furious judge found.

How often does this happen, one wonders, especially in cases without diligent defense lawyers? All five officers are veterans of the force. Now they've been stripped of their police powers, but not fired, the article explains. "There's strong evidence it was conspiracy to lie in this case, for everyone to come up with the same lie," said Judge Catherine Haberkorn. "Many, many, many, many times they all lied."
